moaning and phonation
My husband has bulbar onset ALS. He experiences laryngeal spasms which have produced some strange problems. One thing is that he makes grunting sounds that are associated with movement. Most of us slightly hold our breath (valsalva) for a second when we strain - situps, in the bathroom, lifting... because of bulbar problems, my husband cannot close the glottis to create that internal pressure. So, the passage of air through the vocal cords makes the noises when he rolls over, gets up, strains in any fashion. He also moans, long moans, at night. The moan will be for the entire exhale...and it is a slow exhale, longer than a normal out breath. He is having laryngeal spasms when that happens, with the vocal cords coming together and the air passing though on the exhale makes this long, drawn out phonation. Sometimes, when he's just sitting there relaxed, he will make some odd short little sounds - these seem to be related to the presence of a small amount of mucous that needs to be cleared from his airway. If he uses the cough-assist machine at these times, the sounds stop. I think his body senses the problem but it has not reached his conscious awareness yet, not until it reaches the point that he would need to actually cough (which he cannot do very well by himself and so uses the machine). I'm not medically trained, but this seems to be what goes on here.
